Through the dynamic mechanical experimental tests of recycled aggregate concrete (RAC) prisms confined by transverse hoops, the uniaxial compressive strain-strain complete curves of confined recycled aggregate concrete (CRAC) with different recycled coarse aggregate (RCA) replacement ratio (R) under dynamic monotonic loading conditions were obtained. The influence regularities of RCA replacement ratio on the performance of the mechanics and deformation of CRAC were investigated. It is found that for the uniaxial compressive strain-stress complete curves of CRAC, the ascending portions of the curve are basically consistent with each other under various replacement ratios, hoop confinements or strain rates. However, the descending branches exhibit obvious differences. With the increase of the replacement ratio or the strain rate, the descending branch changes in a steepening trend. However, with the increase of the volume stirrup ratio, the descending branch changes obviously in a flattening trend. Through the confinement of the transverse reinforcement, the ductility of RAC, which is slightly lower than that of NAC, is significantly improved. The influence of the replacement ratio on the compressive peak stress and the ultimate strain is not obvious. With the increase of the RCA replacement ratio, the strain rate or the confinement of the hoop reinforcement, the compressive peak strain is increased. According to the changing law of the characteristic parameters related to the stress-strain curve, the model of the influence factor of RCA replacement ratio for the compressive peak strain is initially proposed in this study. In addition, the initial modulus of elasticity of CRAC under various RCA replacement ratios is developed.
